Tilting pairs and Wakamatsu tilting pairs of subcategories over cleft extensions

Guoqiang Zhao, Juxiang Sun

Let be a cleft extension of abelian categories. We prove that the functor preserves and reflects (Wakamatsu) tilting pairs of subcategories…

Silting and tilting objects in cleft extensions of abelian categories

Guoqiang Zhao, Juxiang Sun

We establish connections between silting and tilting objects in an abelian category and those in a cleft extension of , which provides a me…

-Gorenstein projective and -Gorenstein injective modules over tensor rings

Guoqiang Zhao, Juxiang Sun

Let be a tensor ring and , be two classes of -modules. Under certain conditions, we prove that a -module is $Ind(\mathcal{X}…

Construction of Gorenstein projective modules over tensor rings

Guoqiang Zhao, Juxiang Sun

For a tensor ring , we obtain sufficient and necessary conditions to describe all complete projective resolutions and all Gorenstein projective modules. As a consequence, w…

Constructions of symmetric separable equivalences and their applications

Juxiang Sun, Guoqiang Zhao

Let and be symmetrically separably equivalent Artin algebras. We prove that there exist symmetrical separable equivalences between certain endomorphism algebras of module…

Gorenstein categories and separable equivalences

Guoqiang Zhao, Juxiang Sun

Let be an additive subcategory of left -modules, we establish relations of the orthogonal classes of and (co)res under sep…
